Abstract
The crystal packing in well - determined, organic, Z* ≥ 1 † structures in groups #3 ( P 2) and #5 ( C 2/ A 2/ I 2) has been analyzed. The study completes the survey of packing in organic structures archived in the CSD that have R ≤ 0.050 and that were reported in low - symmetry (SG# ≤ 8), low - frequency (< 5000 entries) space groups. Surveys of the structures described in P 11 and in group #7 ( Pc / Pn / Pa ) 2 have already been published. There are only 6 such structures in group #6 ( Pm ) and only 12 in #8 ( Cm ), with a number of those being either suspicious or very inorganic.
